The {{Deprecated template}} template notifies users that a given template has been replaced by a different one. This is useful when usage is different (so a redirect won't work) or you'd like to reduce the number of redirects (which makes bot parsing more difficult).

Whenever possible, it should replace the deprecated template's content entirely, so that someone using the template will see only the message.



{{Deprecated template|old template name|new template name|date=July 2024}}

Usage without a date parameter categorizes templates to Category:Deprecated templates. Adding the date parameter categorizes the template to Category:Deprecated templates from July 2024.

This template changes style depending on what kind of page it is shown on. Thus it adheres to the standardised looks for the different namespaces.

If a deprecated template is still in use on other pages, add <noinclude>...</noinclude> tags around the {{Deprecated template}} template. That way the template page will show the deprecation tag, but pages using it will not. If a template has been fully deprecated, meaning that it not in use on other pages, the noinclude tags may be removed. That way a deprecation tag will show on any page using the deprecated template. Afterwards consider nominating the template for deletion, or marking it with {{Historical template}}.



{{Deprecated template|Old|New|date=July 2024}}

Template loop detected: Template:When on basepage


The template can show parameters as follows:

{{Deprecated template|Old|New|parameter}}

{{Deprecated template|Old|New|<nowiki>parameter=foo</nowiki>}}

Template loop detected: Template:When on basepage

Template loop detected: Template:When on basepage

The template can also show a note:

{{Deprecated template|Old|New|note=Further details can be inserted here}}

Template loop detected: Template:When on basepage

Special parameters for templates outside template namespace.

|old= and |new= can be used with the full names including namespace.

{{Deprecated template|old=Template:Old|new=Wikipedia:New}}

Template loop detected: Template:When on basepage

Category suppression

The template can be prevented from categorizing by adding |nocat=true. In that case not only the page itself will not be categorized, but transclusions of such pages will also be prevented from categorizing in Category:Pages using deprecated templates.
